Description
In spite of undeniable similarities of the applied techniques, rather different challenges are encountered when extracting, from QCD sum rules for two-point correlators of appropriate heavy-light interpolating currents, the decay constants of charmed mesons of, on the one hand, pseudoscalar nature and, on the other hand, vector nature. This observation justifies a careful reassessment of the corresponding findings.
